STIRRUP.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application lled August 6, 1907. Serial No. 387,313.

To all whom it may concern:

Be it known that I, HERMANN KRIEG, a subject of the German Emperor, residing at Neustadt-on-the-Hardt, Kingdom of Bavaria, Em ire of Germany, have invented a new andpuseful Safety-Stirrup, of which the following is a speciiication.

My invention relates to improvements in safety stirrups, the object being to provide a i stirrup and simple coupling device which will securely hold the stirrup under normal conditions and 'will readily and automatically release the stirrup the moment these conditions are changed,

ln the drawing accompanying and forming part of this specification I have shown in detail certain advantageous forms of embodiment of the invention which, to enable those skilled in the art to practice the same, will be set forth in detail in the following description, while the novelty of the invention will be included in the claims succeeding said description.

Referring to said drawing-Figure 1 is an elevation of a stirrup and coupling especially designed for carrying into eiiect the objects of this invention, and Fig. 2 is a partial, vertical, longitudinal section.

Corresponding and like parts are referred.

to in the following description and indicated in the views of the drawings by the same reference characters.

From the usual supporting thong or strap (not shown) is sus ended a coupling comprising a substantial y straight metal shank A having a small loop a formed on one end for the reception of said strap and on the other end are formed short parallel tongues or hooks e" having beveled ends, as clearly shown in Fig. 2. @ne face of the shank is recessed., and an arm B, corresponding in dimensions to the recess, is pivoted on a pin C journaled in the shank. On the free end of arm B is formed a single tongue or hook b having beveled ends and ada ted to it and normally lie between the para lel tongues a. It will, of course, be understood that the same function will be performed by forming two parallel tongues on the arm B and one on the shank A, or one tongue might be formed on the shank and one on the arm, so that the two tongues will lie parallel to each other. Both the shank and arm are recessed above the tongues forming, when the two parts lie together in their normal position, a narrow longitudinal slot D. The arm B is held pressed against the upper recessed portion of the shank by means of a spring E secured to the shank by screws c e. hor the sake of compactness the spring is iiat as shown in E ig. 2, and lies flush with one edge of the shank.

rlhe stirrup here shown consists of the usual metal loop G having a ilat ribbed or corrugated bottom foot rest g. Substantially midway between the top oi the loop and the foot rest is formed a brace bar g preferably arched on its under side to lit over the instep of the rider. The arch or top of the loop is made somewhat wider than is customary, and a slot g2 is so positioned therein with relation to the upper edge of the arch as to form a support or web g3 of substantially thesame crosssection as the slot D.

It will readily be understood that in case of an accident the stirrup is moved at an angle to the longitudinal plane of the coupling, the support g3 will be rotated and act as a cam against the two walls of the slot D, rocking the arm B on its pivot and separating the hooks of the shank and arm. The curved edges of the support in their turned position lie on the beveled ends of the hook, and the slightest pull on the stirrup will cause the support to act as a wedge and further spread the hooks, resulting in the ready release of the stirrup. As the bar g3 is in close relation to the top of the foot, the slightest movement of the foot out of its normal position will, through the meduim of' the bar, rock the stirrup and effect its release.

I claim- 1. In a device ofthe character described, a pair of articulated supporting members having overlapping ends and recessed to form a longitudinal slot, in combination with a stirrup having a supporting web of substantially the same dimensions as the slot, whereby the rotation of the web will act as a cam on the articulated members.

2. In a device ofthe character described, a pair of articulated supporting members having interlocking beveled ends and recessed to form a longitudinal slot, in combination with a stirrup comprising a loop having a slot therein to receive said overlapping ends, and a supporting web above the receiving slot of substantially the same dimensions as the longitudinal slot.

3. In a device ofthe character described, a pair of articulated supporting members having interlocking beveled ends and recessed abovezsaidxgendsgto formjllongitudinal slot CJi between them, in combination with a stirrup having a supporting web rounded on its edges and of substantially theA same dimensions as the slot, for the purpose specified.

4. In a device of the character described, a pair of articulated supporting members having beveled hook-shaped interlocking ends and recessed above said ends to form a slot between them, in combination with a s'tirrup having a supporting web rounded on its edges and of substantially the same dimensions as the slot, and a brace-bar intermediate of the top and bottom of the stirrup.

5. In a device ofthe character described, a shank having a hook formed on one end, an arm pivoted on the shank having a hook formed on its free end adapted to overlap the aforesaid hook and provided with a longitu-l dinal recess corresponding to a recess formed in the shank, a flat spring xed to the shank covering the arm, in combination with a stirrup comprising a loop having a transverse slot therein to receive said hooks, and a supporting web above the transverse slot rounded on its edges and of substantially the same dimensions as the combined recesses, and a transverse brace intermediate oi the top and bottom oi the stirrup.

In witness whereof I have hereunto set my hand in presence of two witnesses.
